Spontaneous uterine rupture is lethal in pregnant women. Placenta percreta-induced spontaneous uterine rupture in the first trimester is extremely rare and difficult to diagnose. A 35-year-old pregnant woman, with a history of 2 vaginal deliveries and 2 spontaneous abortions treated by dilatation and curettage, was admitted to the emergency department because of sudden severe abdominal pain; the gestational age as calculated by sonography was 14 weeks. Diagnostic laparoscopy was considered for surgical abdomen and fluid collection that was noted in sonography. During laparoscopy, uterine rupture with massive bleeding was detected; therefore, total abdominal hysterectomy was performed. The patient was discharged without any complications. Pathological analysis of the uterine specimen revealed placenta percreta to be the cause of the rupture. Uterine rupture should be considered in the differential diagnosis in all pregnant women who present with acute abdomen, show fluid collection in the peritoneal cavity. In addition, we recommend laparoscopy for the investigation of acute abdomen with unclear diagnosis in the first trimester of pregnancy.

An amniocele is a herniation of the amniotic sac through a uterine defect. Uterine rupture during pregnancy may develop as a result of a pre-existing injury, uterine anomaly, or unscarred uterus. A 30-year-old patient, with a history of 2 vaginal deliveries, presented an amniocele complicated by left fundal perforation and was evaluated with 3-dimensional ultrasound at 23 weeks. Because of worsening lower abdominal pain and vaginal bleeding, she underwent exploratory laparotomy. Herein, we report a uterine rupture with amniocele.
